.SH DESCRIPTION
|
|
\fB\*L\fP
|
|
is a program that will let you to present a variety of questions or
|
|
display messages using dialog boxes from a shell script.
|
|
These types of dialog boxes are implemented
|
|
(though not all are necessarily compiled into \fB\*p\fR):

|
|
You can put more than one dialog box into a script:
|
|
.TP 5
|
|
-
|
|
Use the "\fB--and-widget\fP" token to force \fB\*p\fP to proceed to the next
|
|
dialog unless you have pressed ESC to cancel, or
|
|
.TP 5
|
|
-
|
|
Simply add the tokens for the next dialog box, making a chain.
|
|
\*L stops chaining when the return code from a dialog is nonzero,
|
|
e.g., Cancel or No (see DIAGNOSTICS).
|
|
.PP
|
|
Some widgets, e.g., checklist, will write text to \fB\*p\fP's output.
|
|
Normally that is the standard error, but there are options for
|
|
changing this: "\fB--output-fd\fP", "\fB--stderr\fP" and "\fB--stdout\fP".
|
|
No text is written if the Cancel button (or ESC) is pressed;
|
|
\fB\*p\fP exits immediately in that case.
|
|
.
|
|
.\" ************************************************************************
|
|
.SH OPTIONS
|
|
All options begin with "\fB--\fP"
|
|
(two ASCII hyphens,
|
|
for the benefit of those using systems with deranged locale support).
|
|
.PP
|
|
A "\fB--\fP" by itself is used as an escape,
|
|
i.e., the next token on the command-line is not treated as an option.
|
|
.RS
|
|
.B \*p --title -- --Not an option
|
|
.RE
|
|
.PP
|
|
The "\fB--args\fP" option tells \fB\*p\fP to list the command-line
|
|
parameters to the standard error.
|
|
This is useful when debugging complex scripts using
|
|
the "\fB--\fP" and "\fB--file\fP",
|
|
since the command-line may be rewritten as these are expanded.
|
|
.PP
|
|
The "\fB--file\fP" option tells \fB\*p\fP to read parameters from
|
|
the file named as its value.
|
|
.RS
|
|
.B \*p --file \fIparameterfile
|
|
.RE
|
|
Blanks not within double-quotes are discarded
|
|
(use backslashes to quote single characters).
|
|
The result is inserted into the command-line,
|
|
replacing "\fB--file\fP" and its option value.
|
|
Interpretation of the command-line resumes from that point.
|
|
If \fIparameterfile\fP begins with "&", \fB\*p\fP
|
|
interprets the following text as a file descriptor number
|
|
rather than a filename.
|
|
.
|
|
.SS \fBCommon Options\fP
|
|
.
|
|
.IP "\fB--ascii-lines
|
|
Rather than draw graphics lines around boxes,
|
|
draw ASCII "+" and "-" in the same place.
|
|
See also "\fB--no-lines\fR".
|
|
.
|
|
.IP "\fB--aspect \fIratio"
|
|
This gives you some control over the box dimensions when using auto
|
|
sizing (specifying 0 for height and width).
|
|
It represents width / height.
|
|
The default is 9, which means 9 characters wide to every 1 line high.
|
|
.
|
|
.IP "\fB--backtitle \fIbacktitle"
|
|
Specifies a
|
|
\fIbacktitle\fP
|
|
string to be displayed on the backdrop, at the top of the screen.
|
|
.
|
|
.IP "\fB--begin \fIy x"
|
|
Specify the position of the upper left corner of a dialog box on the screen.
|
|
.
|
|
.IP "\fB--cancel-label \fIstring"
|
|
Override the label used for "Cancel" buttons.
|
|
.
|
|
.IP "\fB--clear"
|
|
Clears the widget screen, keeping only the screen_color background.
|
|
Use this when you combine widgets with "\fB--and-widget\fR" to erase the
|
|
contents of a previous widget on the screen, so it won't be seen
|
|
under the contents of a following widget.
|
|
Understand this as the complement of "\fB--keep-window\fR".
|
|
To compare the effects, use these:
|
|
.
|
|

|
|

.IP
|
|
Note, if you want to restore original console colors and send your
|
|
cursor home after the dialog program has exited, use the \fBclear\fR\ (1)
|
|
command.
|
|
.
|
|
.IP "\fB--colors"
|
|
Interpret embedded "\\Z" sequences in the dialog text
|
|
by the following character,
|
|
which tells \fB\*p\fP to set colors or video attributes:
|
|
0 through 7 are the ANSI used in curses:
|
|
black,
|
|
red,
|
|
green,
|
|
yellow,
|
|
blue,
|
|
magenta,
|
|
cyan and
|
|
white respectively.
|
|
Bold is set by 'b', reset by 'B'.
|
|
Reverse is set by 'r', reset by 'R'.
|
|
Underline is set by 'u', reset by 'U'.
|
|
The settings are cumulative, e.g., "\\Zb\\Z1" makes the following text
|
|
bold (perhaps bright) red.
|
|
Restore normal settings with "\\Zn".
|
|
.
|
|
.IP "\fB--column-separator \fIstring"
|
|
Tell \fB\*p\fP to split data for radio/checkboxes and menus on the
|
|
occurrences of the given string, and to align the split data into columns.
|
|
.
|
|
.IP "\fB--cr-wrap"
|
|
Interpret embedded newlines in the dialog text as a newline on the screen.
|
|
Otherwise, \fB\*p\fR will only wrap lines where needed to fit inside the text box.
|
|
Even though you can control line breaks with this,
|
|
\fB\*L\fR will still wrap any lines that are too long for the width of the box.
|
|
Without cr-wrap, the layout of your text may be formatted to look nice
|
|
in the source code of your script without affecting the way it will
|
|
look in the dialog.
|
|
.IP
|
|
See also the "\fB--no-collapse\fP" and "\fB--trim\fP" options.
|
|
.
|
|
.IP "\fB--create-rc \fIfile"
|
|
When
|
|
\fB\*p\fP
|
|
supports run-time configuration,
|
|
this can be used to dump a sample configuration file to the file specified
|
|
by
|
|
.IR file "."
|
|
.
|
|
.IP "\fB--date-format \fIformat"
|
|
If the host provides \fBstrftime\fP,
|
|
this option allows you to specify the format of the date printed for
|
|
the \fB--calendar\fP widget.
|
|
The time of day (hour, minute, second) are the current local time.
|
|
.
|
|
.IP "\fB--defaultno"
|
|
Make the default value of the
|
|
\fByes/no\fP
|
|
box a
|
|
.BR No .
|
|
Likewise, make the default button of widgets that provide "OK" and "Cancel"
|
|
a \fBCancel\fP.
|
|
If "\fB--nocancel\fP" or "\fB--visit-items\fP" are given
|
|
those options overrides this,
|
|
making the default button always "Yes" (internally the same as "OK").
|
|
.
|
|
.IP "\fB--default-item \fIstring"
|
|
Set the default item in a checklist, form or menu box.
|
|
Normally the first item in the box is the default.
|
|
.
|
|
.IP "\fB--exit-label \fIstring"
|
|
Override the label used for "EXIT" buttons.
|
|
.
|
|
.IP "\fB--extra-button"
|
|
Show an extra button, between "OK" and "Cancel" buttons.
|
|
.
|
|
.IP "\fB--extra-label \fIstring"
|
|
Override the label used for "Extra" buttons.
|
|
Note: for inputmenu widgets, this defaults to "Rename".
|
|
.
|
|
.IP "\fB--help"
|
|
Prints the help message to the standard output and exits.
|
|
The help message is also printed if no options are given,
|
|
or if an unrecognized option is given.
|
|
.
|
|
.IP "\fB--help-button"
|
|
Show a help-button after "OK" and "Cancel" buttons,
|
|
i.e., in checklist, radiolist and menu boxes.
|
|
If "\fB--item-help\fR" is also given, on exit
|
|
the return status will be the same as for the "OK" button,
|
|
and the item-help text will be written to \fB\*p\fP's output after the token "HELP".
|
|
Otherwise, the return status will indicate that the Help button was pressed,
|
|
and no message printed.
|
|
.
|
|
.IP "\fB--help-label \fIstring"
|
|
Override the label used for "Help" buttons.
|
|
.
|
|
.IP "\fB--help-status"
|
|
If the help-button is selected,
|
|
writes the checklist, radiolist or form information
|
|
after the item-help "HELP" information.
|
|
This can be used to reconstruct the state of a checklist after processing
|
|
the help request.
|
|
.
|
|
.IP "\fB--hfile \fIfilename"
|
|
Display the given file using a textbox when the user presses F1.
|
|
.
|
|
.IP "\fB--hline \fIstring"
|
|
Display the given string centered at the bottom of the widget.
|
|
.
|
|
.IP "\fB--ignore"
|
|
Ignore options that \fB\*p\fP does not recognize.
|
|
Some well-known ones such as "\fB--icon\fP" are ignored anyway,
|
|
but this is a better choice for compatibility with other implementations.
|
|
.
|
|
.IP "\fB--input-fd \fIfd"
|
|
Read keyboard input from the given file descriptor.
|
|
Most \fB\*p\fR scripts read from the standard input,
|
|
but the gauge widget reads a pipe (which is always standard input).
|
|
Some configurations do not work properly when
|
|
\fB\*p\fP tries to reopen the terminal.
|
|
Use this option (with appropriate juggling of file-descriptors)
|
|
if your script must work in that type of environment.
|
|
.
|
|
.IP "\fB--insecure"
|
|
Makes the password widget friendlier but less secure,
|
|
by echoing asterisks for each character.
|
|
.
|
|
.IP "\fB--item-help"
|
|
Interpret the tags data for checklist, radiolist and menu boxes
|
|
adding a column which is displayed in the bottom line of the
|
|
screen, for the currently selected item.
|
|
.
|
|
.IP "\fB--keep-tite"
|
|
Normally \fB\*p\fP checks to see if it is running in an \fBxterm\fP,
|
|
and in that case tries to suppress the initialization strings that
|
|
would make it switch to the alternate screen.
|
|
Switching between the normal and alternate screens
|
|
is visually distracting in a script which runs \fB\*p\fP
|
|
several times.
|
|
Use this option to allow \fB\*p\fP to use those initialization strings.
|
|
.
|
|
.IP "\fB--keep-window"
|
|
Normally when \fB\*p\fR performs several \fBtailboxbg\fR widgets
|
|
connected by "\fB--and-widget\fR",
|
|
it clears the old widget from the screen by painting over it.
|
|
Use this option to suppress that repainting.
|
|
.IP
|
|
At exit, \fB\*p\fR repaints all of the widgets which have been
|
|
marked with "\fB--keep-window\fR", even if they are not \fBtailboxbg\fR widgets.
|
|
That causes them to be repainted in reverse order.
|
|
See the discussion of the "\fB--clear\fR" option for examples.
|
|
.
|
|
.IP "\fB--max-input \fIsize"
|
|
Limit input strings to the given size.
|
|
If not specified, the limit is 2048.
|
|
.
|
|
.IP "\fB--no-cancel"
|
|
.IP "\fB--nocancel"
|
|
Suppress the "Cancel" button in checklist, inputbox and menu box modes.
|
|
A script can still test if the user pressed the ESC key to cancel to quit.
|
|
.
|
|
.IP "\fB--no-collapse"
|
|
Normally \fB\*p\fR converts tabs to spaces and reduces multiple
|
|
spaces to a single space for text which is displayed in a message boxes, etc.
|
|
Use this option to disable that feature.
|
|
Note that \fB\*p\fR will still wrap text,
|
|
subject to the "\fB--cr-wrap\fR" and "\fB--trim\fR" options.
|
|
.
|
|
.IP "\fB--no-kill"
|
|
Tells
|
|
\fB\*p\fP
|
|
to put the
|
|
\fBtailboxbg\fP
|
|
box in the background,
|
|
printing its process id to \fB\*p\fP's output.
|
|
SIGHUP is disabled for the background process.
|
|
.
|
|
.IP "\fB--no-label \fIstring"
|
|
Override the label used for "No" buttons.
|
|
.
|
|
.IP "\fB--no-lines
|
|
Rather than draw lines around boxes, draw spaces in the same place.
|
|
See also "\fB--ascii-lines\fR".
|
|
.
|
|
.IP "\fB--no-mouse
|
|
Do not enable the mouse.
|
|
.
|
|
.IP "\fB--no-nl-expand
|
|
Do not convert "\\n" substrings of the message/prompt text into
|
|
literal newlines.
|
|
.
|
|
.IP "\fB--no-ok"
|
|
.IP "\fB--nook"
|
|
Suppress the "OK" button in checklist, inputbox and menu box modes.
|
|
A script can still test if the user pressed the "Enter" key to accept the data.
|
|
.
|
|
.
|
|
.IP "\fB--no-shadow"
|
|
Suppress shadows that would be drawn to the right and bottom of each dialog box.
|
|
.
|
|
.IP "\fB--ok-label \fIstring"
|
|
Override the label used for "OK" buttons.
|
|
.
|
|
.IP "\fB--output-fd \fIfd"
|
|
Direct output to the given file descriptor.
|
|
Most \fB\*p\fR scripts write to the standard error,
|
|
but error messages may also be written there, depending on your script.
|
|
.
|
|
.IP "\fB--separator \fIstring"
|
|
.IP "\fB--output-separator\fIstring"
|
|
Specify a string that will separate the output on \fB\*p\fP's output from
|
|
checklists, rather than a newline (for --separate-output) or a space.
|
|
This applies to other widgets such as forms and editboxes which normally
|
|
use a newline.
|
|
.
|
|
.IP "\fB--print-maxsize"
|
|
Print the maximum size of dialog boxes, i.e., the screen size,
|
|
to \fB\*p\fP's output.
|
|
This may be used alone, without other options.
|
|
.
|
|
.IP "\fB--print-size"
|
|
Prints the size of each dialog box to \fB\*p\fP's output.
|
|
.
|
|
.IP "\fB--print-version"
|
|
Prints \fB\*p\fR's version to \fB\*p\fP's output.
|
|
This may be used alone, without other options.
|
|
It does not cause \fBdialog\fP to exit by itself.
|
|
.
|
|
.IP "\fB--scrollbar"
|
|
For widgets holding a scrollable set of data,
|
|
draw a scrollbar on its right-margin.
|
|
This does not respond to the mouse.
|
|
.
|
|
.IP "\fB--separate-output"
|
|
For checklist widgets, output result one line at a time, with no quoting.
|
|
This facilitates parsing by another program.
|
|
.
|
|
.IP "\fB--separate-widget \fIstring"
|
|
Specify a string that will separate the output on \fB\*p\fP's output from
|
|
each widget.
|
|
This is used to simplify parsing the result of a dialog with several widgets.
|
|
If this option is not given,
|
|
the default separator string is a tab character.
|
|
.
|
|
.IP "\fB--shadow"
|
|
Draw a shadow to the right and bottom of each dialog box.
|
|
.
|
|
.IP "\fB--single-quoted"
|
|
Use single-quoting as needed (and no quotes if unneeded) for the
|
|
output of checklist's as well as the item-help text.
|
|
If this option is not set, \fB\*p\fP uses double quotes around each item.
|
|
That requires occasional use of backslashes to make the output useful in
|
|
shell scripts.
|
|
.
|
|
.IP "\fB--size-err"
|
|
Check the resulting size of a dialog box before trying to use it,
|
|
printing the resulting size if it is larger than the screen.
|
|
(This option is obsolete, since all new-window calls are checked).
|
|
.
|
|
.IP "\fB--sleep \fIsecs"
|
|
Sleep (delay) for the given number of seconds after processing a dialog box.
|
|
.
|
|
.IP "\fB--stderr"
|
|
Direct output to the standard error.
|
|
This is the default, since curses normally writes screen updates to
|
|
the standard output.
|
|
.
|
|
.IP "\fB--stdout"
|
|
Direct output to the standard output.
|
|
This option is provided for compatibility with Xdialog,
|
|
however using it in portable scripts is not recommended,
|
|
since curses normally writes its screen updates to the standard output.
|
|
If you use this option, \fB\*p\fR attempts to reopen the terminal
|
|
so it can write to the display.
|
|
Depending on the platform and your environment, that may fail.

A

\fBtext\fP
|

box lets you display the contents of a text file in a dialog box.

It is like a simple text file viewer.
|
|
The user can move through the file by using the
|
|
cursor, page-up, page-down
|
|
and \fIHOME/END\fR keys available on most keyboards.
|
|
If the lines are too long to be displayed in the box,
|
|
the \fILEFT/RIGHT\fP
|
|
keys can be used to scroll the text region horizontally.
|
|
You may also use vi-style keys h, j, k, l in place of the cursor keys,
|
|
and B or N in place of the page-up and page-down keys.
|
|
Scroll up/down using vi-style 'k' and 'j', or arrow-keys.
|
|
Scroll left/right using vi-style 'h' and 'l', or arrow-keys.
|
|
A '0' resets the left/right scrolling.

vi-style forward and backward searching functions are also provided.

the current date's corresponding values are used.

A \fByes/no\fP dialog box of

The string specified by

HPUX curses (and perhaps others) do not open the terminal properly for

whiptail(1) is a lightweight replacement for \*p(1),

|
to provide dialog boxes for shell scripts. It is built on the

newt windowing library rather than the ncurses library, allowing
|
|
it to be smaller in embedded enviroments such as installers,

rescue disks, etc.

Comparing actual sizes (Debian testing, 2007/1/10):

The total of sizes for \fBwhiptail\fP, the newt, popt and slang libraries is 757kb.

The comparable number for \fB\*p\fP (counting ncurses) is 520kb.

Disregard the first paragraph.

|

The second paragraph is misleading, since \fBwhiptail\fP
|
|
also does not work for common options of \*p, such as the gauge box.
|
|
\fBwhiptail\fP is less compatible with \fB\*p\fP than the decade-old
|
|
original dialog 0.4 program.
|
|

\fBwhiptail\fP's manpage borrows features from \fB\*p\fP, e.g.,
|
|
\fB--default-item\fP (2000),
|
|
\fB--output-fd\fP (2002),
|
|
but oddly cites only \fB\*p\fP versions up to 0.4 (1996) as a source.
|
|
That is, its manpage refers to features which
|
|
were borrowed from more recent versions of \fB\*p\fP, e.g.,
|
|
the \fB--gauge\fP and \fB--password\fP boxes,
|
|
as well as options such as \fB-separate-output\fP (2008).
|
|
Somewhat humorously, one may note that the \fBpopt\fP feature
|
|
(undocumented in its manpage)
|
|
of using a "--" as an escape was documented in \fB\*p\fP's manpage about
|
|
a year before it was mentioned in \fBwhiptail\fP's manpage.

\fBwhiptail\fP's manpage incorrectly attributes that to \fBgetopt\fP
